Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553508, here are decompositions:

5 + 31553503 = 31553508
139 + 31553369 = 31553508
149 + 31553359 = 31553508
157 + 31553351 = 31553508
229 + 31553279 = 31553508
307 + 31553201 = 31553508
331 + 31553177 = 31553508
347 + 31553161 = 31553508

Showing the first eight; more decompositions exist.
